Gram-negative, slightly  curved cells, 1 x 2.3-5 µm, motile by at least one polar
flagellum.
Colonies on TSA are translucent, non-swarming, convex, smooth, rounded, beige,
2.5-3 mm in diameter after 48 h at 28 ºC. Colonies are yellow, transparent, umbonate,
round with scalloped margins, wavy, shiny, 3
mm in diameter on TCBS agar after 24
hours at 28 ºC.
Can grow in nutrient broth with: 2.5% and 6% NaCl. No growth in 0% NaCl, 8% NaCl
and 10% NaCl. Optimal growth at  30-35 °C. No growth at 4 ºC or 40 ºC. Facultative
anaerobe. No luminescence produced.
Isolated from larvae of the bivalve Nodipecten nodosus in Brasil.
Sensitive to vibriostatic agent O/129, resistant to Kanamycin.
Unknown.
